Post the make and model of your monitor and whether it whines. If it does, describe the degree, nature and conditions. As this log grows, everyone can benefit by using it as a quick reference. When it gets big enough, we will turn it to a table with multiple models, samples and ratings, and keep it up to date.

BenQ G2400W (bought Sept 2008) -- 24" value LCD monitor. At turn-on, whines with a high pitched single tone when brightness is reduced to 90 or lower (0-100 scale). It's very low in level (volume) but still audible from 2' in front of the screen. The volume of the whine tends to get louder as brightness is further reduced. After it's been on for a while (10 min? 20 min?) the level of whine goes down so it's almost inaudible when set above ~75.

Gateway FPD2185W - when brightnes is below 90+/-5 it whines easy to hear and annoying, whine is heard even from few meters away from monitor in all directions. i had few of them and all have this issue.

NEC MultiSync 20WGX2 - dead silent on all brightnes levels. its makes very, very quiet whine in standby mode and its only heard very close to the back of monitor.

Acer AL2216Wbd - Emits a low buzz whenever displaying its own "Acer" startup splash image or "No Signal" image just before shutdown below 85% brightness. Other than that, this monitor is only seen and not heard.

Acer AL1916WAbd - The 22" model's little brother does have a moderate level of very high frequency whine below 95% brightness. Mercifully, it slowly fades as it warms up, and after 20-30 minutes of use, it's completely silent. I first noticed the whine ~8 months after purchase. Emits the same buzz as its big brother under the same conditions.

Completely unrelated, but although these two monitors look identical, just scaled larger or smaller, the 19" takes 4-5 times longer than the 22" to finish its splash screen routine and display the desktop/image. The 19" also takes about that much longer to wake from sleep on moving the mouse after the OS turns the monitor "off".

Planar PL2010M - No noise whatsoever at any brightness setting. This is, however, an older part number; the newer monitors have switched to a lower-quality LCD panel. I don't know whether the backlighting has been changed or not, though.

Gateway FPD1765 - No noise at any brightness. However, there is not enough brightness adjustment available, and even minimum brightness is too high for some situations.

dell 2407wfp- my brothers monitor, makes a rather broadband whine- rather quiet and very tolerable.
benq fp71g+s- silent, though it did die in <3 yrs, also developed a couple of dead pixels.
viewsonic vg2021m- a screamer- completely intolerable and very loud, sold to a friends parents at a big discount.
acer x201w- high pitched but quiet, pops up when the ambient decreases- very annoying late into the night.
dell s2409w- same as the acer above- but a touch quieter.

something else: the dell s2409w is my current monitor, its one of the best tn panels i've ever seen, and the lack of a splash page is a breath of fresh air- it turns on in about a second.

all the monitors that whined did so at anything less than ~100 brightness, the noise usually changed at different settings but not significantly.

Dell 2709W: Unbearable humming noise at every brightness setting.
Samsung 245B: Sounds like a huge transformer station iiyama E1900WS: Whine at all settings except 100%, but not as bad as the other two. About as loud as a 2,5" drive.

NEC LCD2070NX-White/Silver

Virtually silent. Is running at 48% brightness, and 41% contrast, and I have to put my ear within 4" of the vents on the top of the back to hear a very, very quiet, whine. And, BTW, I have the hearing of a dog or bat, and the audiometry results to prove it. No one else in my family can hear this monitor, even at very close range. At any distance from the front, even an inch or so, it is silent, even at night, in a very quiet house (I live in the middle of nowhere, so when it is quiet here, it is very quiet here).

It is also a great monitor in general, with a S-IPS panel, and very good highlight and shadow detail, very good color rendition too.

Unfortunately, what was said about the 2070NX can not be said about the 2090UXi. My hearing is very sharp and I can hear a whine coming out of this monitor regardless of brightness levels. The whine gets louder if there is a white background such as a webpage. I have somewhat remedied this by taping all the side and bottom vents and leaving only the top vents open. This has reduced the whine somewhat. I can only hear the whine when it is very quiet now, but when there is a white background, the whine is noticeable nonetheless. Just about any source of ambient noise will drown out the whine, but it gets very annoying when my room is very quiet.

Noise aside, this is the best monitor I have ever used. The image quality is second to none being that it's S-IPS and this thing has more features than I could ask for. Overall I'm satisfied with it since I don't even notice the whine 95% of the time.

Acer AL1951I currently have it set to 100 contrast, 0 brightness, and I just cycled both settings from top to bottom. I put my ear quite closer to the monitor and didn't hear anything, but the ambient noise in here isn't as low as it could be. I'll try again later.

EDIT: Two or three times now, upon powering up the monitor, I have heard a faint very high-pitched sound. Since it's happened more than once, I'm pretty sure it's not tinnitus. My experience seems similar to what RedAE102 noted about his smaller Acer monitor (AL1916WAbd); the AL1951 seems to quiet itself very quickly as it warms up, though.

An additional unacceptable high whine appear in some documents with horizontal lines. This whine appear at all brightness levels including maximum luminosity. It is a rare event, but very irritating.
Zoom in and zoom out on this image, will result in a change of whine tonality.

Viewsonic VP171s. Very audbile whine while on, brightness setting doesn't really do anything after five years of use. Irritating eep-eep-eep signal while on standby, muted whine while off. Switching power off from master switch cures whine. Nowadays retired.

Benq G2400W. What Mike said. Whine has apparently become more quiet over time, now usable with 60 Brightness, 50 Contrast in Photo mode with only mild discomfort at times.

Bought 11 months ago. Virtually inaudible regardless of the brightness setting (presently at 25%). Not completely, though - I can just make out a very quiet whine when I put my ear (literally) on the back vent.

_________________Can you keep it down? I'm having trouble hearing the artillery.

Acer P223W Ws ( White ) 22" Quiet on default setting. I could not hear whine or so when reducing brightness but my game rig isn't as quiet as mainrig. But still I haven't yet heard anything annoying on my Acer. Just ambedient so far.

dell 2001FP had very slight hum from the power brick, screen was inaudible. power brick had long cord and could be hidden away in a cupboard somewhere

dell 2007FP same noise level as 2001fp but power brick was integrated into the back of the panel, so noise could no longer be relocated still pretty quiet and probably only noticable for those with an inaudible pc

dell 3008WFP buzz at any brightness, significantly louder than the dell 20"

LG L2000CP-SFNo audible noise, but is located at my workplace, where air conditionig noise kills everything. Fortunately no high-pitch whine (specifically checked by younger co-workers ), what is often big problem for this model according to many reviews.

Samsung 932B+ 19", TN, non-widescreen. Silent but does produce a faint psu hum audible within 30-50cm if placed on a lightweight surface. Silent across its brightness range with no perceptible whine. 8 months old.
